Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that when the subject
vehicles are exposed to high ambient temperatures in combination with frequent stop and go driving
small cracks may develop over time in the fuel filt er module assembly due to mechanical stress. Fuel
evaporation through these small cracks may lead to cu stomer complaints of fuel smell and evaporative
emissions standards may be exceeded. Dealers will check the fuel filter module assembly and repair or
install an improved fuel filter module assembly if necessary. Mercedes-Benz USA, LLC (MBUSA) has
therefore initiated a Voluntary Emissions Recall Campaign.

Attached is a sample copy of a letter which ow ners of the affected vehicles will receive.

Prior to performing this Recall Campaign:
• Please check VMI to determine if the vehicle is involved in the Campaign and if it has been
previously repaired.
• Please review the entire Recall Campaign bulletin and follow the procedure steps exactly as
described.

Please note that Recall and Service Campaigns do not expire and may also be performed on a vehicle
with a vehicle status indicator.

Approximately 8,011 vehicles are involved.

Order No. P-RC-2008020001
This bulletin has been created and maintained in accordance with MBUSA-SLP S423QH001, Document and Data
Control, and MBUSA-SLP S424HH001, Control of Quality Records.
